HVAC PUMP
Overview
Grundfos end-suction pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation.
Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation.
The Grundfos NB/NBG pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The NB/NBG range consists of close-coupled pumps with their main dimensions in accordance with either EN733 or ISO2858.
Applications
Grundfos offers a virtually limitless range of close coupled (NB) end-suction pumps. Their sturdiness and reliability make them ideal for use in demanding environments such as the following:
- District heating plants
- Heating systems for blocks of flats
- Air-conditioning systems
- Cooling systems
- Wash down systems
- Other industrial systems.
Features and benefits
- Optimised hydraulics in housing and impeller = unimpeded liquid flow
- O-ring seal between pump housing and cover = no risk of leakage
- Housing, impeller and wear ring in different materials = improved corrosion resistance, no sticking elements
- Pump is CED coated to increase corrosion resistance
- Available with IE1, IE2 and IE3 motors
- Available in a number of shaft seal and material variants
- PN 10,16 and 25 bar
- For temperatures up to 140 °C.
Overview
THIS PUMP WANTS TO COMMUNICATE!
INTELLIGENT COMMUNICATION IS PART OF EVERY TPE3
More input, ACCESSORIES
more output
With a number of configurable relays and analog inputs,
the complete TPE3 I/O package allows for better system
monitoring and optimal pump regulation. The TPE3 I/O
package includes
• 2 x analog input for differential pressure sensor,
constant/differential temperature control, heat energy
metering or external set-point
• 2 x relay output configurable as alarm, ready, operation,
pump running or warning
• 1 digital input and 1 digital input/output for external
start/stop, max/min curve, alarm reset, multi-pump
function with wireless communication between TPE3
pumps in parallel or as twin pumps.
BUILT-IN HEAT ENERGY MONITOR FOR COMPLETE CONTROL
The TPE3 features a built-in heat energy monitor that can monitor heat energy distribution and
consumption. and help avoid excessive energy bills caused by system imbalances.
• Measure current energy consumption, flow rate and much more.*
• Avoid the cost of installing a separate heat energy metering device within your system
• Integration with BMS gives you a quick overview of the performance of your system
(available as extra functionality)
• Can be used in a wide range of applications, from Ground Source Heat Pumping and solar to
more traditional applications like heating and cooling.
Pumps for life: TP and TPE
TP and TPE are the ultimate choice in In-line pumps. These
highly adaptable, intelligent pumps are extremely efficient
and built to match your needs perfectly.
TP: Comes with the highly efficient IE3 Grundfos Blueflux®
motor as standard.
TPE: Features both the IE3 Grundfos Blueflux® motor as
well as an integrated frequency converter that ensures
maximum efficiency at all times. All TPE components are
tailor-made and mutually optimised, resulting in energy
savings of up to 50% compared to conventional pumps.
TPD/TPED: Twin-head pump variants of the TP and the TPE.
Advantages of an integrated
frequency converter
• Easy commissioning
• Easy installation – no need for cabling
• Preset solution for quick and safe installation
• Space saving
• Motor, frequency converter and motor
protection in one
• Software optimised for pump operation
– low operation costs
• One supplier, one warranty
